Wow, that's weird, wish my AMD would do speeds like that :) As for your temperature observation - I have no idea sorry. It would appear= =20 that powerd is doing the right thing but for some reason your CPU is not=20 benefiting. That said checking by measuring temperature is fraught with=20 complexity because there is probably a significant delay between a change i= n=20 power consumption and a corresponding chaange in heatsink temperature. =2D-=20 Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C --nextPart2146451.dPc6vQSXtl Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQBDxfGV5ZPcIHs/zowRAijzAJ9uJXaQ0XgIV9UYoxtpaZw3Te+PdwCgnn6M ATwdNzY5Sy2tbhV0r+v7tEc= =eAO2 -----END PGP SIGNATURE----- --nextPart2146451.dPc6vQSXtl--
